Huh?
If your in the EC just drag your bandaids to yer hotbar than right click them and set the target to cursor or stored or whatever it is your trying to do.
If its a mage heal....its the same process.
In the classic client you can also set a bandy macro to heal yourself w/o UO assist but with UO Assist you can record whatever macro it is you need to make. Up to 99 lines I think.
I`ve used UOA to make a single button macro to cross heal a friend or whatever.
Theres no macro sites,since they are so easy to do in either client. If you don`t have UOA,its only $15 and its a one time fee.
